IMPRQVEMENT IN NUT-LIGUE.

The Schedlx'eferrc t'o in these Lettera Patent and making part ofthesame.

To all l20h-mn yit may locmw-rn:

Be it known that I, J. HYDE Eiserne, of Chicago, in the county of `Cook,and State of Illinois, have invented n useful Improvement for FasteningNuts on v Bolts; and I do hereby declare that the/following is et full,clear, and exact description thereof, reference being had to theaccompanying drawings, and letters marked thereon, making n part of thisspecification, in which- Figure 1 is :t representation of nuts securedwith my improved fastener.

Figure 2, t perspective viev'fof the back side of the' The washer, tig.2, is ont from any suitable material,

in the usual manner; :tnd then, by meansof :t die, or other suitabletool, it is so countersunk on one side as to form small projections [lb, which fit into corresponding depressions lt b', runde in themetel-plnte et iig. 3.

By this means, the washer has so firm aiseat that when it is turnednp-ztt its edges, :ts shown at E E,

fig. 1, it will prevent the nut D from turning on the screw H.

Then the washerhas alseat on wood, or other soft material, it is notnecessary to forin the depressions shown atti b with n tool, as the nutD, when properly turned on, Iwill force the depressions d b, fig.' 2, inand hold the washer.

Having thus described myv invention,

That I claim, end desire to secure kby Letters Pntent of the UnitedStates, isf- In combina-tion with the nut D and screw H, a. Washer, C,which is so formed to have projections d t fitting into correspondingdepressions d b in its seat, as set forth. J. HYDE FISHER. Titnessesg G.L. CHAPIN, E. E. GIBSON.
